The micrOphone is now being used
in Germany for the purpose of detect
ing loss of water through leakage in
town mains. The apparatus consists
of steel rod, which is placed upon the
cock in the neighborhood of which the
leak is suspected, and a microphOne
attached to the upper end of the rod
A dry battery and telephone completes
the equipment. No sound is heard in
the telephone if the cocks are closed
and no leak occurs; but a leak even of
few drops through u badly-titting
cock causes sufficient vibration in the
pipe to affect the microphone, and give
audible sounds in the telephone.-EIec-
